It is about a year since my secret addiction started, a balmy Summer Saturday when, due to the sheer laziness of not wanting to reach down to the coffee table for the remote, I found myself doing something I hadn't consciously done for at least 20 years: watching an episode of Doctor Who.

A programme that brings together children, their nostalgic parents, grandparents and normal (!) women like me? That's pretty rare. A programme that does it all with an eccentrically sexy male lead? Even better.
